This object is a count of the number of octets
contained in normal priority frames that have been
received on this port. This counter is incremented
by OctetCount for each frame received on this port
which is counted by icfVgPortNormPriorityFrames.
Note that this counter will roll over very quickly.
It is provided for backward compatibility for Network
Management protocols that do not support 64 bit
counters (e.g. SNMP version 1).
